Answer:

(x + 7)^2 + (y + 3)^2 = 4

Step-by-step explanation:

The standard equation of a circle is:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center and r is the radius. We can substitute the information given to obtain:

(x + 7)^2 + (y + 3)^2 = 4

Which best describes the transformation from the graph of f(x)2 to the graph of f(x)=(x-3)2-1

____ [38]

The giving functions are from dofferent types. transforming a function does not change it's type so it is impossible to transfer f(x)=2 to f(x)=(x-3)^2-1.

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

a is a leg
b is another leg
c is the hypotenuse

Step-by-step explanation:

Step 1: Define

Identify variables

Leg a = a

Leg b = 12

Hypotenuse c = 20

Step 2: Solve for a

Substitute in variables [Pythagorean Theorem]: a² + 12² = 20²
Evaluate exponents: a² + 144 = 400
[Subtraction Property of Equality] Isolate a term: a² = 256
[Equality Property] Square root both sides: a = 16

At midnight, the temperature was -8oF. At noon, the temperature was 23oF. Which expression represents the increase in temperatur

irinina [24]

Answer:

$23^oF-(-8^oF)$

Step-by-step explanation:

We have been given that at midnight, the temperature was $-8^oF$ . At noon, the temperature was $23^oF$ .

Since our temperature has increased to 23 degree Fahrenheit from -8 degree Fahrenheit, we can represent this increase in temperature as:

$\text{The increase in temperature}=23^oF-(-8^oF)$

Therefore, the expression $23^oF-(-8^oF)$ represents the increase in temperature.
